Dust Scattering Albedo at Millimeter-Wavelengths in the TW Hya Disk
Tomohiro C. Yoshida, Hideko Nomura, Takashi Tsukagoshi +3
Planetary bodies are formed by coagulation of solid dust grains in protoplanetary disks. Therefore, it is crucial to constrain the physical and chemical properties of the dust grai…
Solving Self-calibration of ALMA Data with an Optimization Method
Shiro Ikeda, Takeshi Nakazato, Takashi Tsukagoshi +2
We reformulate the gain correction problem of the radio interferometry as an optimization problem with regularization, which is solved efficiently with an iterative algorithm. Comb…
Outflow Driven by a Protoplanet Embedded in the TW Hya Disk
Tomohiro C. Yoshida, Hideko Nomura, Charles J. Law +4
Gas giant planets are formed by gas accretion onto planetary cores in protoplanetary disks. However, direct evidence of this process is still lacking, limiting our understanding of…
ALMA 2D Super-resolution Imaging of Taurus-Auriga Protoplanetary Disks: Probing Statistical Properties of Disk Substructures
Masayuki Yamaguchi, Takayuki Muto, Takashi Tsukagoshi +6
In the past decade, ALMA observations of protoplanetary disks revealed various substructures including gaps and rings. Their origin may be probed through statistical studies on the…
The First Spatially-resolved Detection of CN in a Protoplanetary Disk and Evidence for Complex Carbon Isotope Fractionation
Tomohiro C. Yoshida, Hideko Nomura, Kenji Furuya +7
Recent measurements of carbon isotope ratios in both protoplanetary disks and exoplanet atmospheres have suggested a possible transfer of significant carbon isotope fractionation f…
